Title: Pll circuit
Inventor: TAKANO HIROSHI
IPC: H03L7/18
Filed: 1987-06-09
Abstract: PURPOSE:To facilitate the discrimination of the synchronizing state and to attain ease of maintenance by generating a gate signal bridged over before and after a recovered clock being the result of frequency-dividing an output of a VCO and detecting whether or not reference clock exists in the signal. CONSTITUTION:A gate signal 10 to be bridged over before and after a time point when the clock 8 exists from a gate signal generator 9 started by the recovered clock 8 from a 1/N frequency divider 1a and a synchronizing detection signal 16 ANDing with a reference clock 7 is generated. An out of synchronism detection means 11 outputs an out of synchronism signal 17 when the signal 16 does not exists in a period when the signal 10 is significant. A backward protection means 12 counts the signal 16 when signals 10,16,17 are generated and discriminates it to be in the phase synchronizing state when the count exceeds a prescribed value. A forward synchronization protection means 13 counts the signal 10 and discriminates it not to be in the phase synchronizing state when the count exceeds a prescribed value. The synchronizing state hold means 14 stores the result of discrimination of the means 12,13 and a display device 18 is lighted or extinguished by the output. Thus, whether or not the phase synchronizing state is reached is confirmed in this way.

Title: Thermal recording paper
Inventor: SUZUKI YOSHIMI
IPC: D21H11/14
Filed: 1990-06-01
Abstract: PURPOSE:To obtain a thermal recording paper having a small winding curl even with the passage of time when wound round a small roll, having a good tray-receivability after recording and giving a clear image at a high concentration by containing a recycle pulp as a support by the specific quantity of the whole pulp and by using the support having a specific density. CONSTITUTION:In a thermal recording material using a coloring reaction between a leuco dye and its developer, there is used a support containing a recycle pulp by 30-90wt.% of the whole pulp and having 0.8g/cm<3> and less density. When the percentage content of the recycle pulp is higher than 90wt.%, an image quality lowers and when the percentage content is lower than 30wt.%, a combining ability between fibers rises, a winding curl grows larger and a tray-receivability worsens. Also, when the density of the support is lower than 0.8g/cm<3>, the combined area of a combination between fibers can be decreased and swelling at the time of water coating can be suppressed to the minimum and the utility of the recycle pulp can be raised. Accordingly, it is possible to obtain a thermal recording paper with good winding curl and image quality.

Title: Horizontal deflection circuit
Inventor: ONOZAWA MAKOTO
IPC: H04N3/16
Filed: 1989-06-08
Abstract: PURPOSE:To suppress the increase in the loss of a modulation output transistor(TR) by connecting a collector voltage control circuit to a collector of a modulation output PNP TR and varying the collector voltage of the output TR in response to the change in the horizontal display size. CONSTITUTION:A modulation voltage detection circuit 104 in a collector voltage control circuit 102 detects a modulation voltage VS and the conduction/ nonconduction of a 1st switch means 36 is switched based on the modulation voltage VS. As a result when the modulation voltage VS is lower than a prescribed voltage VSX, the collector voltage VC of the modulation output TR 27 reaches nearly 0V. When the modulation voltage VS is higher than the prescribed voltage VSX, the collector voltage VC of the modulation output TR 27 reaches a potential depending on a voltage source or the like connected to a current output terminal 37. Thus, the increase in the loss of the modulation output TR being a problem when the horizontal display size is changed can be reduced.

Title: Glass fiber
Inventor: HANAI MASAHIRO
IPC: C03B37/10
Filed: 1995-06-12
Abstract: PURPOSE: To obtain a glass fiber having reliability in insulation by irradiating a glass fiber body with electromagnetic high frequencies, thereby removing the small impurities forming conductive parts. CONSTITUTION: The glass fiber body 1 formed of non-alkaline glass is taken up and is inserted in this state into an electronic cooking device (microwave oven) 2 which is one of high-frequency radio wave generators using magnetrons, by which the glass fiber body is irradiated with the electromagnetic high frequencies. As a result, high-frequency current flows to the conductive foreign matter of a length of several mm or below intruding into the glass fiber body as a part thereof, by which an electric discharge is generated from the ends of the foreign matter to evaporate and splash the foreign matter. The foreign matter is thus removed. The similar effect of removing the conductive foreign matter is obtd. even if the glass fiber body is irradiated with the electromagnetic high frequencies while the fiber body is cooled from the molten state and is taken up.

Title: Temperature rise simulation method in case
Inventor: OTA KOJI
IPC: G01K7/00
Filed: 1996-06-06
Abstract: PROBLEM TO BE SOLVED: To enable highly accurate simulation of risen in temperature within a case with a simple arithmetic processing by including a correction value for temperature rise according to the total of consumed power, specifications of the case and the like in a rising portion in the temperatures of various individual parts arranged in the case. SOLUTION: Temperature rise TC of individual electric parts when a plurality of parts arranged in a case are electrically energized simultaneously, is higher than temperature rise TA when the parts are individually energized, because of effect of heat from other parts. A difference of the temperature rise (about 5 deg.C for a part positioned at the coordinate X5 in an illustrated example) in the simultaneous energization as compared with the individual energization depends on the total of consumed consumed power, the configuration of the parts, deviation of the temperature of parts and the like.  So, as for various parts assembled into the case, the temperature rise corresponding to the degree of electric energization of the individual parts is considered as a correction value corresponding to a rising portion in the temperature obtained in the simultaneous electric energization of a plurality of parts arranged in the case to determine a simulation value of the rise in the temperature of the parts.

Title: Flexible magnetic disk
Inventor: KAMATA KAZUKI
IPC: G11B5/64
Filed: 1990-06-04
Abstract: PURPOSE:To prevent the generation of a crack, and simultaneously, to improve path wear durability by recessing and forming the groove of specified depth concentrically with a track on the rear surface of the intermediate position of the tracks neighboring each other on the other surface of a polymeric film. CONSTITUTION:The U-shaped, V-shaped, W-shaped or like shaped groove or slit 2 whose depth is 30 to 80% of the thickness of the film 7 is recessed and formed concentrically with the track 5 on the rear surface of the intermediate position of the tracks 5 neighboring each other on the other surface 3 of the polymeric film 7. In a state that a magnetic layer 6 is in contact with a head 8, since bending rigidity in a radial direction from the center of a disk 1 is absorbed by the groove or slit 2 recessed and formed on the other surface of the film 7, bending stress is effectively moderated at a contact point of the layer with the corner of the head 8. Accordingly, the generation of the crack can be prevented, and simultaneously, the path wear durability can be improved.

Filed: 1990-06-01
Abstract: PURPOSE:To locally decarburize the centrifugally cast pipe by blowing oxygen for a prescribed period of time in the molten ductile cast iron cast into the inside surface of a rotating centrifugal casting mold before the molten metal solidifies. CONSTITUTION:The melt 7 of the ductile cast iron is cast into the inside surface of the centrifugal casting mold 1 while the mold 1 is kept rotated. An oxygen supplying means (oxygen lance) 8 is inserted into the mold 1 before the molten metal 7 solidifies. The oxygen supplied from the oxygen supplying means 8 is then acted for a specified period of time to the molten metal at both ends of pipe to remove the C in the molten metal 7 near both ends of the pipe. The quantity of the C at both ends of the cast pipe is decreased in this way and job site welding work is facilitated. The usefulness of the piping operation of the ductile cast iron pipe is thus improved.

Title: Musical sound signal generating device
Inventor: KUNIMOTO TOSHIFUMI
IPC: G10H7/08
Filed: 1989-06-07
Abstract: PURPOSE:To enable the musical sound signal generating device to operated with a fixed clock when generating a musical sound signal by using a cyclic delay circuit by providing a delay phase control means to make to coincide the repetitive cycle of waveform data by the storage part and phase fine adjustment part of a delay means with the cycle of a generated musical sound signal. CONSTITUTION:The time from the storage to the output of waveform data from the storage means 32 of the delay means is an integral multiple of a constant time interval and intervals of repetitive output do not match one cycle of a waveform possible only by the storage part 32, but the phase fine adjustment part 33 which is provided together with the storage part 32 shifts the waveform data in phase by a proper time under the control by the delay phase control mean. Consequently, cycles which are outputted repeatedly by the storage part 32 and phase fine adjusting part 33 on the whole is made coincident with the cycle of a desired musical sound signal. Consequently, when the musical sound signal is generated by using the cyclic delay circuit, the musical sound signal of desired pitch is obtained even with the fixed clock.

Title: Information processor
Inventor: WAKAI TETSUYA
IPC: G06F12/08
Filed: 1979-11-08
Abstract: PURPOSE: To enhance the process efficiency, by lowering the frequency to repeal the contents of a buffer memory and increasing the bit factor of the buffer memory.  
     CONSTITUTION: The processor extracts both the memory contents alteration time 12 and the processor information 13 out of the task control block 11. The comparator 25 compares the information 13 with the processor number register 23, and delivers the signal to the AND gate 27 when no coincidence is obtained. On the other hand, the comparator 26 compares the time 12 with the buffer repealing time 24 which shows the time when the buffer memory 3 incorporated into the allotted processor is repealed last. In case the time 24 is less than the time 12, the signal is sent to the gate 27. Then the gate 27 transmits the buffer memory repealing signal in case the signals are transmitted from the comparators 25 and 26. Thus the frequency to repeal the buffer memory is reduced to increase the process capacity.
